Crystal Units
NX2012SA
For OA / AV / Mobile Communications
Features
■
Ultra compact, thin, and light weight tuning fork crystal unit.
● Excellent heat resistance and environmental characteristics.
● Excellent electric performance optimum for mobile communications,
OA (office automation) and AV (audiovisual) applications are exhibited.
● RoHS compliant. These can meet the requirements of re-flow profiling using lead-
free solder.
● Use a metal lid: Excellent shock resistance during chip mounting process
comparing to a glass lid.
